Yingfang Liu, Professor
中國科學院生物物理所 百人計劃,研究員
1993-1999年: 畢業於北京大學植物分子生物學系研究生,獲博士學位
1999-2005年: 先後在美國國立猶太醫學研究中心免疫學系、冷泉港實驗室以及杜克大學醫學中心從事博士后及研究助理工作
2005年至今:生物物理所研究組長,研究員
劉迎芳研究員於1999年在北京大學獲得理學博士學位。在美國的博士后研究期間,主要從事結構生物學研究,對一些重要蛋白,例如SarA,SarR,TALL-1及其受體,進行結構和功能研究,取得多項重要研究成果。
2005年回國后加入生物物理所後主要從事於衰老與凋亡相關蛋白的結構生物學研究工作。主要內容為:1.凋亡細胞吞噬的分子機制研究。凋亡細胞的吞噬主要有兩條相互并行的通路介導,一是由CED-1,CED-6,CED-7和CED-14參與的信號途徑,另一個是由CED-2,CED-5,CED-12和CED-10介導。我們對這一通路相關蛋白開展結構生物學研究工作,以期揭示這一重要通路中各分子的作用機制以及通路的調節機制。2. 癌症相關蛋白、細胞衰老及凋亡過程中表觀遺傳學的結構生物學研究。主要研究衰老及凋亡過程中染色體修飾的改變以及在基因表達調控中的作用,研究癌症分子機制。3. 重大傳染病特別是流感病毒聚合酶結構生物學研究等。
September 1993- May 1999: Graduate student, Dept. of Plant Molecular Biology, Peking University, P.R. China.
August 1999- February 2005: Postdoctoral Associate, National Jewish Medical and Research Center, W. M. Keck Structural Biology Laboratory, Cold Spring Harbor Laboratory and Duke University Medical Center.

Dr. Yingfang Liu obtained his doctor degree on Plant Science in Peking University, 1999. In his postdoctoral training period in USA, he was mainly working on structure biology and engaged in structural and functional studies of some very important proteins, such as SarA, SarR, TALL-1 and its receptors and had got plenty of results.
Currently, Liu’s lab is mainly working on structural biology studies of some proteins related to cancer, aging and apoptosis. Some main projects are: 1. Structural and functional studies of proteins involving in cell corpse engulfment. Two redundant pathways have been identified for cell engulfment, one includes CED-1, CED-6, CED-7 and CED-14; the other includes CED-2, CED-5, CED-12 and CED-10. We are working on structural studies of these proteins in order to reveal their possible roles in the processes. 2. Structural study of epigenetic modification in cancer, aging and apoptosis processes. 3. Structural and functional study of influenza virus polymerase.
